    Trane has had some issues with combustion motors on some units.

    Hi Dave,
    The motor is bad, it has shorted internally winding to winding causing it to run continuously.
    You must replace the motor.

    Do you have a local contractor to call for this service?

    Good Luck,

    Might want to actually diagnose the motor and power circuit before replacing any parts..

    We dont even know what model unit he has, it was just a guess that it was a Voyager.

    Yes.

    Get a good commercial tech out to look at it.

    Trane did have some service bulletins on combustion motors and associated parts.

    Allens right the motor is shorted internally winding to winding, i've seen this at least 5 times. use an ohm meter to check windings you'll see whats going on, the assembly for this is around ********** thats the discounted price if you have an account. you can always let it go until it fails....trane always has these motor assemblies in stock. good luck

    Pricing not allowed, please.

    You can't let it go. It'll cause the HX to fill with condensation in the summer.

    yes you should, preferably a Trane factory rep. yes they did, you may get it covered under the service bulletin.
    It's hard to stop a Trane. but I have made one helluva living keeping them going.

    You should refrain from giving unprofessional advice like this.

    The OP needs to have the unit repaired correctly and not have to plug and unplug a motor seasonally.

    There are a couple of different things that could cause the problem and it requires a professional to diagnose it.


    You should work on getting your post count up and apply for Professional Membership.
